It says it will…
USB Input: 5V A male; DC Output: 12V; Max current: 2A;
I do have reservations though. Are you feeding this from a ‘Wall Wart’, or a computer USB because
12V x 2A = 24W
24W / 5V = 4.8A
So whatever you use needs to be able to supply 5A@5V to be up to the job without blowing something. Computer ports usually supply nowhere near this current. See my comments here.
My advice would be to get a >3A 12V DC Wall Wart and use that to supply the Router. Damage to your computer due to drawing too much current through the USB could be a problem as they are usually specced quite low and are meant for periherals.
